- 1Basic principles of VAC therpayvacuum assisted closed, non-invasive, active, wound-closure system
controlled by negative pressure, to promote healing in acute and chronic wounds - 2VAC micro/macro strainmicrostrain - what you can't see
macrostrain - what you can see, biological response, draws wound edges together, removes infectious material, reduces oedema, promotes perfusion
micro- negative pressure creates tissue microdeformation that lead to cell stretch, granulation tissue formation - 3VACdraws wound edges toegther
closed moist environment
faster granulation tissue formation - 4Contraindications for VACmalignancy, osteomyelitis, necrosis, non-enteric, fistula, exposed blood vessels
- 5precautions for VACactive bleeding, difficult wound haemostasis, anticoagulant therapy, weakened blood vessels, organs, bone fragments, sharp edges,
- 6planning and defining wound treatment objectiveaims:
remove exuduate, reduce local periwound oedema, increase local microvascular blood flow test, promote formation of granulation tissue, reduce complexity and size of wound, optimise wound bed prior to surgery, reduce complexity of surgical wound closure - 7Granufoam - dressing retains open-cell structureopen- cell structure during therapy
assists granulation tissue formation due to reticulated open cell structure
well -suited to highly exudate, infectious wounds, increase drainage capacity
allows uniform distribution of negative pressure
multiple sizes and shape - 8four options of dressin typesVAC granufoam - all open wounds, uniform distribution of pressure, hydrophobic
Granufoam silver - infected wounds, microbonded, reduced pathogen in 24 hours
whitefoam - sensitive wounds, tunnels, underminsed, controlled granulation rate, superficial wounds, increased density, hydrophillic, pre-moistened with sterile water
NPWT gauze dressing - sensitive wounds, tunnels, undermined, controlled granulation rate, superficial wounds - 9sensat rac technologyremoves exudate, which contain material that inhibit wound healing, help maintain consistent environment, monitors pressire, feedback system, 2 sensors monitor target pressure at wound site
- 10changing of VAC dressingsonce every 48-72 hours, but no less than three times a week
infected wounds may need more dressing changes - 11VAC VERAFLO therapy may help toincrease granulation rate
reduce trips for debridement and wash out
decrease hospital stay - 12VAC THERAPY CONTRAINDICATIONSDo not use hydrogen peroxide based solutions, do not deliver fluids to thoracic or abdominal cavities as this can later core body temp and fluid retention
Do not use unless wound is thoroughly explored - 13When to discontinue VACgoals have been met
wound shows no progress for 1-2 weeks - 14dressing techniques for VACgetting a seal - use small pieces, get seal check, cut hole at least 2.5 cm, document numer of pieces of foam used
- 15dressing removealturn off VAC, allow dressing to relax
administer analgesia, count pieces of foam removed, - 16ADAPTICprotects the wound, minimise pain and maceration
non-adhering dressing, knitted cellulose acetate mesh, impregnated with petrolatum emulsion
ADAPTIC TOUCH - non-adhering silicone dressing, flexible openmesh, fluid management, minimise pain
